Kick-Ich is a scientifically developed water treatment, which was proven effective during two years of national test marketing, for stopping C. irritans and I. multifiliis infections. The KICK-ICH formulation is specifically designed to interrupt the free swimming stage (i.e., the tomite stage) of their life cycles, thereby stopping progressive infection and reinfection, without use of copper, malachite green, hyper-irritants or other chemicals that are toxic to many aquarium inhabitants. In addition, KICK-ICH does not affect nitrifying bacteria (e.g., Nitrosomonas and Nitrobacter) and is biodegradable.
